According to the beta migration doc http://docs.ionic.io/docs/migration-guide:
"Ionic.User now requires the implementation of Ionic.Auth into your application."
Why has this been introduced? We have an angular app which uses a custom oauth implementation using cordova's inappbrowser. As such we do not have an email or password to associate to the current user. In the previous version I could arbitrarily create new users based on our unique ID for that user. Is there no supported way for this…

For now i have not been able to Authenticate user before save… I can’t make use of Ionic.Auth.signup because Auth is undefined in my case…
